sMOOTHING-IRON.

Specification forming part of Letters Patent No. 18,108, dated September1, 1857; Reissued January To all whom it may concern:

Be it known that I, WILLIAM F. SHAW, of Boston, in the county of Suffolkand State of Massachusetts, have invented a new and useful or ImprovedApparatus for Heating 21 Flat-Iron; and I do hereby declare that thesame is fully described and represented in the following specificationand the accompanying drawings, of which Figure 1 denotes an elevation ofthe said apparatus. Fig. 2, a vertical and transverse section of thesame. Fig. 3, a top view of the stand on which the flat-iron issupported. Fig. 4, a longitudinal section of the flat-iron, the samebeing taken through its flues and parallel with its smoothing face. Fig.5, is an elevation of the flat iron and exhibits its outlet passages.Fig. 6, is a rear elevation of the flat-iron made to show the inletpassage.

In these drawings, A represents an air and gas burner inclosed within acase or placed directly under a stand B, which is made with a dischargeopening or neck as shown at a. The burner is of the Argand kind orconstructed so as to have an inner air tube Z), by which air may beconducted into the interior of the flame, caused by the combustion ofair and gas on an annular perforated or wire gauze cap a, situated onthe top of an air and gas receiving chamber f, surrounding the tube 6,and made open at the bottom to receive air. A tube 9 for supplying thechamber f, with inflammable gas may lead into it in any proper manner.The cap 0 is surrounded by a perforated or wire gauze tube (Z, whichextends from it as shown in Fig. 2. It also has another wire gauze orperforated tube 6, extending up from the inner air current tube 6, andarranged concentrically with *the tube aZ. Each of the said tubes (Z and6 should be made with numerous holes extending through its entire sidesso as to permit many small streams of air to flow through the sides ofthe said tube into the flame which may be on or near the cap when theapparatus is in operation. The two tubes, 03 and e operate togethergreatly to improve the heating powers of the flame and prevent theformation of aldehyde and formic acid or noxious vapors or gases. Theheat and volatile products of coombustion pass off through the surfaceor neck of the stand and enter the body of the flat-iron placed on thestand and over the said neck, as shown at a, in the drawings.

The flat iron is constructed with a chamber or flue space D, arrangedwithin its body and provided with an inlet opening 70, disposed in theheel of the iron. The flue space is also furnished with one or moredischarge passages or outlets as shown at Z, Z. This flue space asrepresented in Fig. 4 of the drawings is divided by two partitions m, m,into one ascending and two descending flues h, 2' i, the latter twohaving outlets Z, Z made laterally through the iron at their lower ends.The smoothing iron might be made with one single ascending and onesingle descending flue, but I prefer two descending flues, as they serveto eifect a better or more even distribution of the heat over thesmoothing surface of the iron. Without such flues that part of the ironin proximity to its nose or front end would become Very much more heatedthan the heel of the iron, and consequently would be likely to gurn anarticle on which it might be use The stand is made with a projection orrest n, for sustaining the handle of the iron such rest being arrangedso as to cause the iron to take an inclined position as shown in -Figs.1 and 2, whereof it is caused to heat to better advantage than when itstands up right.

By my invention a fiat iron or smoothing iron may be heated to greatadvantage and little cost by means of gas burned with air as specified.

I do not claim heating a fiat iron by means of a lamp having its wicktube or the flame of its wick within the body of the iron; nor do Iclaim heating a flatiron by charcoal or other fuel burned in a chambermade within the body of the iron; nor do I claim herein, the applicationof a wire gauze or perforated chimney to an air and so as to be usedWith a burner and stand in gas burner, so as to surround the flame asmanner substantially as specified. 10 such has heretofore been patentedby me; In testimony whereof I have hereunto set but my signature.

What I do claim is W. F. SHAW. Making the flatiron with ascending and vWitnesses: v descending fines, inlet and discharge open- R. H. EDDY,ings arranged in the body of the iron and F. P. HALE, Jr.
